Abstract

"PROCESSOS PARA A PREPARAçãO DE áCIDO ACRìLICO E DE ACRILATO". A invenção está relacionada a processo para a produção de ácido acrílico ou ésteres de ácido acrílico, a qual compreende a etapa A e opcionalmente as etapas B e C, como se segue: A: resfriar uma mistura gasosa de reação formada durante o processo de oxidação em fase gasosa para a produção de ácido acrílico e que contém ácido acrílico, usando um solvente inerte com alto ponto de ebulição, para produzir uma mistura gasosa contendo ácido acrílico; B: separar a mistura gasosa contendo ácido acrílico para produzir uma fração com baixo ponto de ebulição, um ácido acrílico bruto e um produto de fundo, e C: esterificar o ácido acrílico bruto obtido na etapa B usando um ou mais alcanóis para obter uma mistura da esterificação contendo um ou mais ésteres do ácido acrílico e um ou mais ésteres do ácido acético.
